All-printed smart structures: a viable option? John O’Donnella, Farzad Ahmadkhanloub, Hwan-Sik Yoon*a, Gregory Washingtonb aDept. of Mechanical Engineering, The University of Alabama, Box 870276, Tuscaloosa, AL, USA 35487-0276; bDept. of Mechanical and Aerospace Engineering, University of California Irvine, Irvine, CA, USA 92697-3975 ABSTRACT The last two decades have seen evolution of smart materials and structures technologies from theoretical concepts to physical realization in many engineering fields. These include smart sensors and actuators, active damping and vibration control, biomimetics, and structural health monitoring. Recently, additive manufacturing technologies such as 3D printing and printed electronics have received attention as methods to produce 3D objects or electronic components for prototyping or distributed manufacturing purposes. In this paper, the viability of manufacturing all-printed smart structures, with embedded sensors and actuators, will be investigated. To this end, the current 3D printing and printed electronics technologies will be reviewed first. Then, the plausibility of combining these two different additive manufacturing technologies to create all-printed smart structures will be discussed. Potential applications for this type of all-printed smart structures include most of the traditional smart structures where sensors and actuators are embedded or bonded to the structures to measure structural response and cause desired static and dynamic changes in the structure. Keywords: printed smart structures, 3D printing, printed electronics, printed strain sensor 1. INTRODUCTION Decades of research and development have seen the progression of a variety of different additive manufacturing processes [1]. From basic Fused Deposition modeling to the more intricate Energy Beam methods, the ability to print a diverse selection of structures, both complex and simple, on demand with accuracy and precision has become a reality. -
High Speed Sintering for 3D Printing Applications
High Speed Sintering for 3D printing applications High Speed Sintering for 3D printing applications Neil Hopkinson, Adam Ellis, Adam Strevens, Manolis Papastavrou and Torben Lange, Xaar plc Introduction High Speed Sintering (HSS) is a transformational inkjet-based 3D printing technology which is being further developed at Xaar by the original inventor, Prof. Neil Hopkinson. This 3D printing (also called Additive Manufacturing) technology involves depositing a fine layer of polymeric powder, after which inkjet printheads deposit a single IR (infrared) absorbing fluid directly onto the powder surface in the required cross-sectional pattern where sintering is desired. The entire build area is then irradiated with an infrared lamp, causing the printed fluid to absorb this energy and then melt and sinter (consolidate) the underlying powder. This process is then repeated layer by layer until the build is complete. The use of digital inkjet printing makes the process considerably faster than point based systems, for example those requiring a laser to sinter/melt material. As with all 3D printing processes there is no requirement for new moulds, plates or other design template related fixtures. High Speed Sintering is a self-supporting process; this means that solid, hollow and complex shapes with internal features are possible without the need to create and subsequently remove support structures, at much higher speeds than other additive manufacturing processes. Today there are many 3D printing technologies and several other sintering technologies available. This paper demonstrates how High Speed Sintering (HSS) fits in the 3D printing space as a fast and cost-effective route to develop and manufacture customised prototypes and products. -

Symposium CH01: Frontiers of In Situ Materials Characterization—From New Instrumentation and Method to Imaging Aided Materials Design Advancement in synchrotron X-ray techniques, microscopy and spectroscopy has extended the characterization capability to study the structure, phonon, spin, and electromagnetic field of materials with improved temporal and spatial resolution. This symposium will cover recent advances of in situ imaging techniques and highlight progress in materials design, synthesis, and engineering in catalysts and devices aided by insights gained from the state-of-the-art real-time materials characterization. This program will bring together works with an emphasis on developing and applying new methods in X-ray or electron diffraction, scanning probe microscopy, and other techniques to in situ studies of the dynamics in materials, such as the structural and chemical evolution of energy materials and catalysts, and the electronic structure of semiconductor and functional oxides. Additionally, this symposium will focus on works in designing, synthesizing new materials and optimizing materials properties by utilizing the insights on mechanisms of materials processes at different length or time scales revealed by in situ techniques. Emerging big data analysis approaches and method development presenting opportunities to aid materials design are welcomed. Discussion on experimental strategies, data analysis, and conceptual works showcasing how new in situ tools can probe exotic and critical processes in materials, such as charge and heat transfer, bonding, transport of molecule and ions, are encouraged. The symposium will identify new directions of in situ research, facilitate the application of new techniques to in situ liquid and gas phase microscopy and spectroscopy, and bridge mechanistic study with practical synthesis and engineering for materials with a broad range of applications. -

In this process, gold nanoparticles were simultaneously formed through photoreduction whilst polymerisation of two possible monomers was promoted. The monomers, trimethylopropane triacrylate (TMPTA) and pentaerythritol triacrylate (PETA) were mixed with a gold salt, but it was found that the addition of a ruthenium(II) complex enhanced both the geometrical uniformity and integrity of the polymerised/reduced material, enabling the first production of 3D gold-polymer structures by single step multiphoton lithography. -
Near-Field Multiphoton Nanolithography Using an Apertureless Optical Probe
Invited Paper Near-Field Multiphoton Nanolithography Using an Apertureless Optical Probe Xiaobo Yin, Nicholas Fang, Xiang Zhang* Department of Mechanical and Aerospace Engineering, University of California Los Angeles, Los Angeles CA, 90095 Ignacio B. Martini and Benjamin J. Schwartz Department of Chemistry and Biochemistry, University of California Los Angeles, Los Angeles, CA, 90095-1569 ABSTRACT Near-field multiphoton optical lithography is demonstrated by using ~120 fs laser pulses at 790 nm in an apertureless near-field optical microscope, which produce the lithographic features with ~ 70 nm resolution. The technique takes advantage of the field enhancement at the extremity of a metallic probe to induce nanoscale multiphoton absorption and polymerization in a commercial photoresist, SU-8. Even without optimization of the resist or laser pulses, the spatial resolution of this technique is as high as λ/10, nearly a factor of two smaller than the previous multiphoton lithography in the far field. Keywords: near field, multiphoton, lithography 1. INTRODUCTION There has been great recent excitement over the development of techniques for exceeding the diffraction limit in high-resolution optical imaging and photolithographic nanometer-scale device fabrication. In particular, there have been two different approaches to improving optical resolution below the limits dictated by diffraction. The first approach takes advantage of the nanoscale aperture of a near-field scanning optical microscope (NSOM) probe[1-3], while the second approach is based on the non-linear absorption of light by a chromophore exposed to an intense electromagnetic field [4,5]. The NSOM approach to improved spatial resolution takes advantage of the small, nanometer-sized aperture formed by a metal-coated optical fiber tip from which light can be either directed to or collected from the sample.
